汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)由(you)原油(you)(you)(you)(you)(you)(you)(you)分(fen)餾及(ji)重質餾分(fen)裂(lie)(lie)化(hua)(hua)(hua)制(zhi)得(de)。原油(you)(you)(you)(you)(you)(you)(you)加工過(guo)程中，蒸餾、催(cui)化(hua)(hua)(hua)裂(lie)(lie)化(hua)(hua)(hua)、熱裂(lie)(lie)化(hua)(hua)(hua)、加氫裂(lie)(lie)化(hua)(hua)(hua)、催(cui)化(hua)(hua)(hua)重整、烷(wan)(wan)基化(hua)(hua)(hua)等單元都產出汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)組(zu)分(fen)，但辛(xin)烷(wan)(wan)值(zhi)不同(tong)(tong)，如直餾汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)辛(xin)烷(wan)(wan)值(zhi)低，不能單獨作為發動機(ji)燃料；此外(wai)，雜(za)質硫含量(liang)(liang)也不同(tong)(tong)，因(yin)此硫含量(liang)(liang)高(gao)的汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)組(zu)分(fen)還需(xu)加以脫硫精制(zhi)，之(zhi)后，將上(shang)述汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)組(zu)分(fen)加以調(diao)合，必要時需(xu)加入(ru)高(gao)辛(xin)烷(wan)(wan)值(zhi)組(zu)分(fen)，得(de)到符合國家標準的汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)產品。根(gen)據制(zhi)造過(guo)程，汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)組(zu)分(fen)可分(fen)為直餾汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)、熱裂(lie)(lie)化(hua)(hua)(hua)汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)（焦(jiao)化(hua)(hua)(hua)汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)）、催(cui)化(hua)(hua)(hua)裂(lie)(lie)化(hua)(hua)(hua)汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)、催(cui)化(hua)(hua)(hua)重整汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)、疊合汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)、加氫裂(lie)(lie)化(hua)(hua)(hua)汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)、烷(wan)(wan)基化(hua)(hua)(hua)汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)和合成汽(qi)(qi)油(you)(you)(you)(you)(you)(you)(you)等。

  汽(qi)油(you)(you)產品根據(ju)用(yong)(yong)(yong)途可分為(wei)航空(kong)汽(qi)油(you)(you)、車(che)(che)用(yong)(yong)(yong)汽(qi)油(you)(you)、溶劑(ji)汽(qi)油(you)(you)三大類。前兩者(zhe)主要用(yong)(yong)(yong)作(zuo)汽(qi)油(you)(you)機的(de)燃料，廣泛用(yong)(yong)(yong)于汽(qi)車(che)(che)、摩(mo)托車(che)(che)、快(kuai)艇、直升飛機、農林業(ye)用(yong)(yong)(yong)飛機等。溶劑(ji)汽(qi)油(you)(you)則用(yong)(yong)(yong)于合成橡膠、油(you)(you)漆(qi)、油(you)(you)脂(zhi)、香料等生產；汽(qi)油(you)(you)組分還可以溶解油(you)(you)污(wu)等水無法溶解的(de)物質，起(qi)到清潔油(you)(you)污(wu)的(de)作(zuo)用(yong)(yong)(yong)；汽(qi)油(you)(you)組分作(zuo)為(wei)有(you)機溶液，還可以作(zuo)為(wei)萃取(qu)劑(ji)使用(yong)(yong)(yong)。
